Google yesterday released the first beta of Chrome 10, touting the new version's faster JavaScript engine.

According to tests run by Computerworld, Chrome 10 is 64% faster than its predecessor on Google's own V8 JavaScript benchmarks. Google shipped the stable version of Chrome 9 earlier this month.

Google maintains three separate "channels" of Chrome -- stable, beta and dev -- that denote increasingly rougher-edged editions.

But in another JavaScript benchmark -- WebKit's widely-cited SunSpider -- Chrome 10 beta was no faster than Chrome 9. WebKit is the open-source project that develops the browser engine by the same name; both Chrome and Apple's Safari rely on the WebKit engine.
